But users only have to run this once. This would probably been done at installation time.
Or you have to force the users on computers without these files to download and install it once.

Thank you very much for your great help.
I changed from /MD to /MT, and it works!

This program is to be called by an uninstaller to manipulate the registry. So it wouldn't fit for making a setup for this program though. Blush | :O

But you could add it to the requirements at install time - then it would be there (and not be uninstalled, AFAIK) at uninstall time.

If you just want to print the file in text format, what about using "stdprn"?

Hi Using system is one of the way to handle this, but this method is not generic for other types of devices like scanner or USB stick etc.

We know that any device should be opened then read/write and finally to be closed. Can we write a C++ code to open any device and read/ write into it (e.g. printer) ?

With thanks in advance.

Identifying a corrupt exe

vipin_nvk28-Aug-07 1:15

28-Aug-07 1:15

Hello

My code copies an exe onto a USB flash drive using normal File copy functions, however it is quite possible that the USB flash drive might get disconnected during file copy and may not be copied properly (hence gets corrupted) So, when the user plugs in the USB flash drive next time he / she wont be able to use it. Is it possible programatically to identify a corrupted exe once the exe has been copied onto the USB flash drive ?

Thanx

Checksumming (e.g. MD5). Tools like MD5sum are readyly available in the internet.
But the corrupted exe will very properly not start, so it can't check itself.

Although there is no Direct way to do this, letme specify some alternatives.

1. calculate the Check sum of the File before you save and validate it after your file copy operation is complete. (Less Error prone but effective)

2.Verify the Size of the file copied.

Inside ntdll.dll

Waldermort28-Aug-07 1:04

28-Aug-07 1:04

Can anybody tell me why I'm unable to step inside ntdll with the MS debugger?

I am trying to hook NtCreateSection and replace the section with my own, but I'm getting access violation return codes. So I try stepping into the mthod in order to see what is going on, but I immediatly land on a JUMP instruction and get thrown back out. The code then fails with an "unable to read this address" pop-up. Stepping over the call causes no problems.

Anyway, I have a section created from a file with the PAGE_READONLY flag set, I tried changing this to PAGE_WRITECOPY which succeeds but I'm still unable to map the section. ( No access rights ). But the section is created with ALL_ACCESS_RIGHTS.

Any ideas?

You can, but there won't be much to see as most of it just contains code to transition to kernel mode (where a user mode debugger can't follow).

Yeah, I figured that out after decompiling the dll. I never found the solution to the problem though, I have a feeling the DACL was being set high while the section was being passed between user/kernel modes, preventing me access to it.

C++/MFC GDI Fonts.

Please any one can tell me what is lfOrientation in LOGFONT structure. i can't find any visible difference by changing any values of it. output is mostly same. my code is as bellow,

for (int i=0; i<3600; i+=150) {
LOGFONT lf;
::ZeroMemory (&lf, sizeof (lf));
lf.lfHeight = 2400;
lf.lfWeight = FW_DEMIBOLD;
lf.lfEscapement = i;
lf.lfOrientation = 600; // No change of any value
::lstrcpy (lf.lfFaceName, _T ("Times New Roman"));

CFont font;
font.CreatePointFontIndirect (&lf);

CFont* pOldFont = dc.SelectObject (&font);
dc.TextOut (0, 0, CString (_T (" This is my Output")));
dc.SelectObject (pOldFont);
}

as far as i know, orientation refers to angle wrt. x axis.
not sure weather degrees or radians.
try it out by gradually incrementing the the values from 0 to 360 in a loop.

i tried it but it won't work and Angle is given by lfEscapement member of LOGFONT structure.

Re: C++/MFC GDI Fonts.

chandu00428-Aug-07 0:41

both refer to angle only but with some difference.
you can refer the following url
